GAR-DOOR DEVICE.

Specification. of Letters Patent.

Patented Feb. 8,1916.

Application filed April 3, 1915. Serial No..19,021.

- To all whom it may concern:

Be it known that we, WiLLIAM C. MAR- citizens of the United States,andresidents of Albany, Albany county, New York, have invented certainnew and useful Improvements in Car-Door Devices, of which thefollowing-is a specification. j

- Our invention relates to devices or appliances to be attached tofreight car or other sliding doors foiysecuring them in position and forprovidihglneans for sealing or looking them. Its object is to providesimple, cheap durable, easily secnrable and eiiicient means to theseends.

In the drawings, which 'represent a' preferred form of our device,Figures 1 and 2 are respectively a top plan view and an elevationthereof; Fig. 3 is a partial inverted plan view; Fig. dis a verticalsection through the plane H, Fig. 2; Figs. 5 and 6 are perspective viewsof detached parts.

1-1 designates a car, having door opening 12, door 13 and stile 14. Ondoor 13 is secured, as by bolts 15, the bolt or staple carrying portion16 of the device comprising a body 17 and a strap end 18. Body 17 has acentral arched member 19 between two flanges 20, member 19 having atransverse semi-circular depression 21. From lower flange 20 projects a.raised lug 22, clearly shown in Fig. 3, having a vertically disposedmember 23 pierced with an aperture 24. A. strap portion 25 is superposedon body 17 and'is formed with a semi-circular depression 26,complementary to depression 21' and with bolt apertures registering withthose in flanges 20, see Fig. 4. On stile 1 1 is bolted a combinedstriker, guide and bolt socket 27, shown detached in Fig. 5, having astriker flange 28 on the door side of the stile, a right-angled flange28 at the opposite side and provided with .a bolt hole 30, the member 31con necting these flanges being extended to form a flange 32 having arounded face 33 adapted to pass under arched member 19 and to engageover door 13 to guide it,

body 39, having at one end a head -10, and

' this strap portion and secured to door 13.

adjacent its other end an L-shaped engagmg and lookii'lg portioncomprising a laterally projecting stem 41 and a fiat memher or lug 4:2apertured at =l3 extending transversely from stem 411, 2'. 6.,substantially parallel with body 39.

The parts are assembled as shown in the drawings, it being seen thatbody 39 of bolt'38 is placed in depression 21 before portion 25 issuperposed on body member 19, so that bolt body 39 has free movement indepressions 21 and 26, and the same bolts 15, see Fig. 3, pass throughboth flanges 20 and those in portion 25, so that bolt 38 are firmly Theoperation of the device is clearly shown in the drawings. Bolt 38 beingturned so as to bring member 12 upward, as in dotted lines, Fig. 2, door13 is forced against stile 1-l. flange 32 engaging over the edge of thedoorythe bolt is then moved to the left of Figs. 1, 2 and 3, so as to'withdrawal of the bolt flfom member 34.

It is obvious that many mechanical alterations may be made in the devlcewithout departing from our lnvention, as c. 9., a

mere reversal of the relative position of the parts. It is also clearthat the term car door has no especial significance, and is used toindicate any sliding door wherever used.

, W hat we claim is:

1. A car door fiXture for securing a sliding door to a stile or thelike, comprising a bolt carrying portion secured to one of said carparts and formed with a laterally projecting lug having an aperture; abolt having limited longitudinal and rotary movement 111 said carryingportion and formed with an L-shaped engaging and locking membercomprising a laterally projecting stem and a lug having an aperture andextending transversely from said stem; a socket portion on the other ofsaid car parts adapted to,reccive said bolt and to permit the passage ofsaid L shaped member-when said bolt has been rotated to bring saidmember into one position and to prevent withdrawal of said bolt when ithas been rotated to bring said member into another position; theconstruction of the parts being such that when said bolt has beenrotated to its last-named position said lugs will be brought intosubstantial contact and the apertures therein into registration, wherebythe shackle of a seal or look may be passed through both said apertures.

2. A car door fixture for securing a sliding door to a stile or thelike, comprising a bolt carrying portion secured to one' of said carparts and formed with a laterally projecting lug having an aperture; abolt having limited longitudinal and rotary movement in said carryingportion and formed with a laterally projecting member spaced away fromits free end; a socket portion on the other of said car parts formedwith a U- shaped member adapted to receive said bolt and to permit thepassage of said lateral member when said bolt has been rotated to brinsaid member into one osition and to b a r prevent withdrawal ot saidbolt when it has been rotated to bring said member into anotherposition, and with a second socket apertured to receive the free end ofsaid tures.

3. A car door fikture for securing a sliding door to a stile or thelike, comprising a bolt carrying portion secured to one of said car.

parts and having an arch-shaped head spaced away from said car part; ahoriion- '{tally disposed bolt having limited longitudinal and rotarymotion in said head and formed with a laterally projecting member; acombined guide and socket portion on the other of said car parts havinga member adapted to engage. over the edge of the other car part beneathsaid arched head and a bolt receiving socket adapted to permit thepassage of said boltwhen it has been rotated to bring said projectingmember into one position and to engage with said member after said bolthas been rotated' to bring said memv on the other of said car partshaving a mem-' ber adapted to engage over the edge of said first namedcar part beneath said lug and adapted to permit the passage of said boltand of said projecting member when said bolt has been rotated to bringsaid projecting member into one position and to engage with said memberto prevent withdrawal of said bolt therefrom when it has been rotated tobring said apertures closely adjacent, whereby a shackle may be passedthrough both lsgaid apertures to prevent rotation of said olt.

5. A car door fixture for securing a sliding door to a stileor the like,comprising a bolt carrying portion secured to one of said car parts andincluding an arch-shaped head spaced away from said car part and anindependent, bolt-retaining strap member superposed on and bolted tosaid head; a bolt .having limited longitudinal and rotary movement insaid head and formed witha laterally projecting member; a combined guideand socket portion on the other of said car parts having a flange memberadapted to engage over the edge of said first named car part beneathsaid arched head, and a bolt receiving socket adapted to permit thepassage of said bolt when it has been rotated to bring said projectingmember into one position and to engage with said member after said bolthas been rotated to bring said memher into engaging position.
